Solar wind is a stream of charged particles, which travels through the Solar System at nearly 450 kilometres per second. Solar wind can occur where the magnetic field of the Sun goes into space instead of following its original surface.
Galileo Galilei, the most renowned scientist of the Renaissance period, or the “father of modern science” was known as a jack-of-all-trades: he was an astronomer, physicist, engineer, philosopher, and mathematician just to name a few. But perhaps what he is most known for is spurring the scientific revolution in the late seventeenth century. Galileo challenged what was then considered common knowledge for almost 30 years: for example, the idea of a heliocentric universe. The most controversial of these ideas was embracing the theories of Nicholas Copernicus. Not only did he embrace Copernicus’ ideas, but expanded and substantiated them. The consequences of these actions were multiple trials with the Church regarding his work and later
Alex Grant’s 6 billion kilometer journey to the outer reaches of the solar system was to be the longest continuous spaceflight on record. His spacecraft, Endeavor, was equipped with a solar sail, which harnesses the radiation and particles shooting off the sun - known as solar wind - to propel the ship. The sail, a mirrored
Dr. Micnio Kaku’s article “The Physics of Interstellar Travel” lists many theoretical means of interstellar travel, and the class of civilisations that would be able to harness the amount of energy needed to power such methods of travel, ranging from the energy output of a planet, to the energy output of a galaxy. (Kaku, 2015) The article lists many methods of interstellar travel, including a brief mention of solar sails, but one method, that harnesses the energy output of a galaxy, proves to be the most interesting.
Solar energy has been used for a very long time. The first account of the use of solar energy was from the Greeks. They built their homes in a way that the sun would heat up their houses, even during the cold winters. Ancient Indians also used this method. Let's skip to 1839. In 1839, Edmond Becquerel observed that when certain material was exposed to light, it would create a small amount of electric current. This is the photovoltaic effect(A Brief). This led to John Ericsson developing what he said to be a solar powered steam engine in 1870. Now let’s jump to the late 1950s when a one-watt solar cell costed $300 and a commercial power plant watt cost $0.50 per watt. A scientist was able to demonstrate how a car can
The discovery of the New World brought many irreversible changes not only for the European countries, but to the natives of the land that was being discovered. The sense of exploration began expanding more and more among the European powers. Every time the explorers invaded, they would be more avaricious and aggressive against the natives of the land. Along with diseases and inhumane treatments, the European powers also brought education to the “uneducated” crowds of areas such as India, Africa, and China. The main intention of the foreign powers was to Europeanize the natives of these lands and enslave them into doing the European’s dirty work. To attain such results, the Europeans tried converting the natives’ lifestyles completely. These conversions ranged from substituting the natives’ religion with Christianity, to the way they labored, and to the way they portrayed themselves. All the changes the natives had to go through, are clearly seen in excerpts of Feng Guifen, Afghani, and Gandhi. Each of these men describe the different aspects changed by the Europeans, for instance Feng Guifen describes the education system brought by the Europeans and how that affected Asia. Afghani describes the input of science in Islam, while Gandhi describes the cold heartedness that has spread among the natives and how they have become “civilized.”
Situation Outcome: The Dependent Variable George Bernard Shaw once said, “Progress is impossible without change, and those who cannot change their minds cannot change anything.” Before the Scientific Revolution took place, change was ostracized; their beliefs were practically set in stone by ancient thinkers and were supported up by the powerful church. Lasting from the 16th through the 18th century, Scientific Revolution exhibited individuals challenging tradition; the difference of time period, relationship with the church, and personality affected how Galileo and Copernicus challenged tradition in this era. Born in 1473, Nicolaus Copernicus was a timid mathematician and astronomer connected to the Catholic Church.
The chosen sources are considerably based on Copernicus and Galileo which further reflects the comparison and contrast between both the well-known personalities. However, the first selected source is "Dedication of the Revolutions of the Heavenly Bodies to Pope Paul III”, analyzed and constructed by Nicolaus Copernicus, 1543. Whereas, the second source is “Science and Scripture” by Galileo, 1957. The first source is a primary study. This source is produced by Nicolaus Copernicus. However, this particular study was produced in concerning the revolutions of the heavenly bodies while highlighting the certain motions of the Earth. It has an agenda based
In the following months, the group continued their journey making progress every day through wind and snow. On February 11, 1805, Sacagawea gave birth to a baby boy whom she names Jean Baptiste. April 29, 1805 Lewis and another hunter came across a large grizzly bear, killing it instantly because they were not aware of the animal’s capabilities. Turns out that the grizzly bear had not been described to science and the two men’s discovery changed science. As the warmer weather started to settle in, the Corps of Discovery reached Bitterroot Mountains in late May early June but had to wait until the snow melted to cross. For the time being, the group stayed with the Nez Perce and Lewis described them as “the most hospitable honest and sincere
America, the third largest country in the world, is a place that most people desire to live in. It is filled with fifty states and each with plentiful opportunities spread amongst it. America is considered the "land of opportunity" because it gives opportunities to immigrants that their country cannot provide them with such as: economic stability and educational resources. America is also known today as the melting pot because so many cultures have mixed together in one country to enjoy the same free lifestyle! The important question that everyone should be asking is, who discovered this extraordinary country that everyone enjoys the luxuries of today? To answer that question, Christopher Columbus is credited with the discovery of “The New World” as we know today as America. He is referred to as one of the greatest discovers’ during the Age of Discovery.
“In 1492, Columbus sailed the ocean blue.” Have you ever heard of this famous quote? This quote is about Christopher Columbus and his discovery of the Americas. On the first Monday in October, we celebrate Columbus Day, based on the belief that he discovered the Americas. One might conclude that Christopher Columbus did not discover the Americas because the Native Americans, Vikings, and Phoenicians had already set foot there.
Nicolaus Copernicus was interested in science for a while. He read the work of the Ancient Greeks. In 1513, he bought 800 building stones with the intention of building his own observatory. There Nicolaus would do his work as an astronomer, and make history. In the observatory is where Nicolaus would come up with his famous heliocentric model instead of Ptolemy’s geocentric model. This model will come to be known as what we call today, The Solar System.
On April 21st, 2050, spacecraft Reacher launched out of Houston, Texas. On board was four crew members, each with an extremely important role in the mission; to create a research facility on Europa, one of Jupiter’s many moons. Europa is one of the few places in the entire solar system that scientists predict can support life, due to its tidal fluxing and underground ocean.
